Fallout 4 - Not Responding. Task Manager.

[Church the Cat]

Fallout 4 no longer starts at all. With or without using the Script Extender's launcher. I'm wondering if the latest Windows 10 update is causing it. All I get is a black screen, then the task Manager shows Fallout 4 as "Not responding". (Edit) Fallout4prefs.ini was the culprit. As soon as I moved it from the folder, everything's peachy. I've no idea why, however.
